GEORGE W. BLAKE, OF NEW YORK, N. Y.

IMPROVEMENT IN RADIATORS FOR STEAM-HEATERS.

Specification forming part of Letters Patent No. 156,974, dated November17,1874; application tiled June 13, 1874.

To all whom it may concern:

Be it known that I, GEORGE W. BLAKE, of the city, county, and State ofNew York, have invented a new and useful Improvement in Steam-Radiatorsfor Heating Apartments and other Places or Buildings; and I do herebydeclare that the following is a full, clear, and exact description ofthesame, reference being had to the accompanying drawing forming part ofthis specification, and which represents a vertical section of asteamradiator construct ed in accordance with my improvement.

This invention relates to that description of steam-radiators in which abase divided so as to constitute upper and lower chambers, separate anddistinct from each other, has mount ed upon it a number of radiatingtubes closed at their tops, but in communication at their bottoms withthe upper chamber of the base, and havingarran ged within themsmallertubes open at both ends and in communication at their tops withthe upper spaces of the surrounding larger tubes, and open at theirbottoms to the lower chamber of the base, for the purpose of keeping upa circulation `by means ot' suitable ,openings inthe base for theadmission of steam and escape of water of condensation.

In such radiators it is very desirable to keep the upper and lowerchambers of the base free from water of condensation collecting ineither of them, as well to prevent choking as to avoid any1 bubblingnoise arising from the boiling of said water, and at the same time topreserve the two chambers, as distinct receptacles, intact, so that thecirculation will not be inter fered with.

To these ends, and to insure the more perfect action of the radiator, Icombine, with an opening for the introduction of the steamv to the upperchamber at one end of the base, and

an outlet duct or pipe connecting with the lower chamber at the oppositeend of the base, for escape of the water of condensation, an outsidesmall water-escape branch or pipe at the opposite end of the upperchamber to that through which the steam is admitted, :and connectingwith the outlet-pipe of the lower chamber.

In the accompanying drawing, A represents the base of the radiator,having an upper chamber, B, and lower chamber, C, separate and distinctfrom each other, and provided-#that is, the upper chamber B-with a steaminlet or supply pipe, b, at the one end of the base, and the lowerchamber O witha main outlet pipe or duct, c, at the opposite end of thebase. D D and E E are the outer and inner tubes, mounted on the base andcommunicating with the chambers B and O, as hereinbefore described. .lheupper chamber B is provided, close to its bottom and at the oppositeend, through which steam is admitted, with a small outside branch ortube, d, arranged to connect with the outlet pipe or duct c ot the lowerchamber, and whereby water of condensation is run ottl from the upperchamber by one and the same outlet that carries off the water ofcondensation from the lower chamber, without a break or openingbetweenthe two chambers B O.

' What is here claimed, and desired to be secured by LettersvPatent, is

The combination of the outside water-escape pipe d with the main outletor duct c, the chambers B O, and the steam-inlet b, applied to the baseA ot' a tubular radiator, substantially as specified.
